CHA4863-QGG
RoHS COMPLIANT
17-24GHz Variable Gain Amplifier
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHA4863-QGG is a variable gain
broadband four stage monolithic amplifier.
It is designed for a wide range of
applications,
typically
commercial
communication systems.
The circuit is manufactured with a power
pHEMT process, 0.15µm gate length, via
holes through the substrate, air bridges and
electron beam gate lithography.
It is supplied in RoHS compliant SMD
package.
